What are the two differences in mitosis between plants and animal cells?
There are several differences between plant and animal cells. The most significant difference when viewing these cells through a microscope is the presence of a cell wall in the plant cell as compared to the absence of one in the animal cell. During the process of mitosis a plant forms a cell plate, where a new cell would be formed. Animal cells form a cleavage furrow during cytokinesis when division of the cytoplasm takes place. Another difference is the centrioles which divide and travel to opposite poles of the cells in the beginning of mitosis in the animal cell but in the plant cell they do not have centrioles and still undergo mitosis.
Why does meiosis need to be producing haploid offspring?
Meiosis need to be producing haploid offspring because if they were to produce a diploid offspring then when the offspring is fertilized again and the two gametes fuse to make a normal chromosome number (46 chromosomes), there would be a doubled amount of 96 and each subsequent generation to follow afterwards would also produce a doubled number of chromosomes.
Differentiate homologous chromosomes and sister chromatids.
Homologous chromosomes are two chromosomes that are made from a pair having the same staining pattern, length, and centromere position.
Homologous chromosomes are also called homologs. Compared to the sister chromatids which are the end result of mitosis. They are two copies of one parent chromosome.
